RESILIENT WHEEL.

Specicatien of Letters Patent.

Application led December 12, 1912. Serial No. 736,316.

To all whom, it may concern.'

lle it known that l, OwEN E. CASEY, of Nashua, in the countv of lVilkin and State of Minnesota, have invented certain new and useful 'Improvements in Resilient Wheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enablle Others skilled in the art to which it appertains 'to make and use the same.

This invention relates to improvements in resilient wheels and more particularly to that type in which'the resilience is effected by the construction of the spokes, the object and efficient construction in which the springs of the spokes shall be normally un-f der tension, and in which the parts of the spokes which house said springs shall have pivotal connection, respectively, with lthe hub and the felly.

A further object is t0 so construct the wheel that shocks will be etfectually absorbed. and the smooth and easy running of the vehicle insured.

lVith these and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

ln the accompanying drawings, F igure 1 is a side elevation, partly in section, showing' a portion of a. wheel embodying my improvements; Fig. Q is a sectional view, and F igs. 3 and 'lare detailviews showing one of the tubular members of a spoke.

l represents a pub to receive an axle4 2, and 3 indicates the felly of the wheel on which a tire '-l may be located, said felly being provided with a plurality of recesses 5 and the hub being provided with spaced annular flanges for the aeeomniodatonof attaching means for spokes T, as will be more, fully hereinafter explained. Each spoke comprises two telescoping tubes S--9,-the tube S being open at its outer en d to receive the tube 9 and the latter heilig open at its inner end to accommodate a spring as presently explained. rlhe tube 8 is provided' at its inner end with flaring posed against the inner faces of the parallel flanges 6 on the hub and pivotally connected with said fianges by means of a bolt ll. 'Near its inner end, the tube 8 is provided with a diaphragm 12 having a central angular hole through which a short rod 13 (angular in cross section throughout a portion of its length) passes, the inner portion of said rod being threaded for the accommodation of a nut 14. The upper end of the short rod 13 is provided with a' head 15, to whichthe inner end of a spring 1G is secured. The inner portion of this spring is located Within the tube 8 and said spring is of sutcient length to extend into 'the tube 9, wherein its outer 'end is secured to a disk 17 having a central threaded hole.l The outer end 1S of the tube 9 is provided with la threaded hole to receive the threaded por- -tion of a head 19, the latter being bifurcated to receive one end of a short rod Q0 which is pivotallyconnected with said head by means of abolt or pin 21. Each short rod 20, is provided at its outer end with a head 22 seated in one ofthe recesses 5 in the felly and longitudinal displacement of each rod 20 is prevented by across pin or bolt Q3 which passes transversely through said rod and the felly. A. rod 24. is made rigid with thev head 19 so as to be disposed centrally within the tube 9- and is made with a threaded portion 25 to pass through the threaded opening in the disk 1.7 to which latter, thefouter end of the spring 16 is secured.`

In assembling the Wheel, the operator will turn the rod 24 of each spoke and thus cause the disk 17 to move outwardly within the tube 9 and stretch or put the spring 16 under contractile tension and then secure said rod to the felly in the manner above described. 'lhe springs in the various spokes should be subjected, in this manner` to the same de- `grec of tension, so that. the normal condition of the springs (when not subjected to strain or pressure) will be as illustrated in Fig. l and in the upper portion of Fig. 2.

lirhen the wheel is in use, the weight of the vehicle will permit the springs to approach their closed position and the short atented J uly 1 5, 1913.

'loy

rods to slide freely through the diaphragms 12 when the spokes become disposed under the axle, and the weight will therefore be suspended largely from the springs of the' spokes which are above the plane of the axle, and the major portions of the jars to which the wheel may be subjected will be absorbed by these springs.

Various slight changes might be made in the details of construction of my invention without departing1 from the spirit thereof or limiting its'scope and hence I do not wish to restrict myself to the precise details herein set forth, but

'Having fully described my inventidh what I claim as neviT and desire to secure by Letters-Patent, s:-

' l. In a Wheel,-the combination With a hub and a telly, of a plurality of spokes', each comprising"telescoping tubes, means pivotally connecting one of said tubes with the hub, ahead secured tothe outer end of the other tube, a rod secured to the telly and piyotally connected with said head, a rod secured to the headon one of the tubes and havinga threaded rod disposed Wit-hin said tube, a disk adjustable on said threaded rod, a spring within said tubes and having one end secured to said disk, a short rod connected with the other end of said 'spring and passing through the inner end Wall of the tube connected with the hub, and means for adjusting said short rod and holding it at j, any desiredy adjustment.

2. In a Wheel, the combination with a hub and a telly, the latter having recesses, of a plurality of spokes, each comprising telescoping tubes, each closed at one' end, means connecting one of said tubes With the hub,

springs Within saidetubes, a short rod passing through one end of one of said tubes and secured to one end of said/spring, a rod secured Within the other tube and adjustably connected with the othern end of said spring,

ashor-t rod passing through the felly andhaving a head seated in one of the recesses in the felly, means connecting said rod with the outer tube of the spoke, and a bolt passing transversely through the telly and'sad lastmentioned short rod.

In testimony whereof, I have signed 4this A. J. IITHEY, IVM. J. MCALPEN-.
